According to police documents, Amoa began experiencing contractions in her room at the convent on Oct. 10, 2013. She said the baby was born while she was leaning on her bed. The baby fell straight down, hitting the floor, the documents say.

She initially told police that the baby was born not breathing. However, during a second interview with police six days later, Amoa told officers that she covered the newborn's face because she was scared the nuns would hear him crying.

"She said that she placed a black wool garment over the child's nose and mouth and applied pressure with her hand for two to three minutes," the documents say.

Authorities say she kept the baby in her room overnight, and in the morning, found a nun and told her she'd found the baby outside before later admitting the baby was hers.

They took the baby to Providence Hospital in a black luggage bag.

"It's a very tragic situation for everyone involved," said Sister Constance with Little Sisters of the Poor in a statement last fall. "We're praying for Sosefina and the baby. Because it's now a police investigation, there's nothing else we can say."

While Amoa told police conflicting information at first, she eventually told them she had known she was pregnant. Amoa also admitted that she hadn't told the nuns at Little Sisters about her previous sexual encounters.

An autopsy conducted on the baby determined that he was born at full-term gestation and weighed more than six pounds. The medical examiner said the baby had breathed and had bruises on his nose.
